SCM203 Galvanic Isolator for 4-20mA Current Loop |
(Up) |
|
|
The SCM203 is used to add galvanic isolation to a 4-20mA current loop signal. It also generates a 40-200mV signal for convenient monitoring of the current loop. The unit requires no external power supply, as it is powered from the current loop itself. |
